1 Claim.

This invention relates to a can closing machine, and has for its object to provide a machine adapted to close and seal a can by turntion to be sealed thereby.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a front view of Figure 1.

Figure 4 is a detail inverted plan View of the holding head.

Figure 5 is a section of Figure 4 taken on the line 55 thereof.

Figure 6 is a detail end view of the slotted upright.

Referring to the accompanying drawings, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 2' designates the base of the machine which is secured to a board 2 which latter may be held to a table or stand by clamps to hold the machine securely in position when being operated. The base I has a bearing 3 on one end thereof through which the upright 4 projects. The said upright 4 has a vertical slot 5 extending the entire length thereof into which the end of the screw 6 projects to hold the upright 4 in position and prevent it from turning in the bearing 3 as well as holding it securely in the adjusted position.

Slidably mounted on the upright 4 is an arm 1 having a set-screw 8 which also projects into the vertical slot 5 of the upright 4 and permits the arm 1 to slide up and down on said upright 4 at the same time prevents the arm I from turning on the upright 4. The arm I rests on the upper end of the coiled spring 9 on the upright 4, the lower end of the coiled spring 9 rests on a collar III which is held in position by the pin II. The upper end of the upright 4 is screw-threaded and has a hand wheel 12 screwed thereon and resting against the upper end of the arm I. The said arm 1 can be forced down on the upright 4 by the hand wheel 12 being screwed in one direction and when screwed in the opposite direction the spring 9 will raise the said arm 'I on the upright 4. In the outer end of the arm I is revolubly mounted a shaft l3 having a handle l4 on its upper end and an arm IS on its lower end. Pivoted to the arm l5 at I6 is a lever I! having a threaded boss IS on one end in which the screw l9 operates, said screw I9 has a wheel20 on one end and its inner end impinges against the lever H. The end of the screw I9 is held against the lever I! by the coiled spring 2|, which latter has one end secured to the lever l1 and the other end secured to the arm Hi. In the opposite end of the lever I1 is revolubly mounted a wheel 22 which rests against the flange 23 of a ring 24, the said ring 24 rests on the top of the can and has the flange 23 projecting down in position to be forced under the flange of the can 25. The

shaft l3 has a head 21 on its lower end which rests on the top of the can and holds it in position during the operation of sealing the can. This head 21 does not revolve with the shaft l3 but is free thereon. As the handle I4 is turned the lever I1 is carried around the can 25 and the wheel 22 forces the flange 23 inwardly on each turn of the lever I1, each revolution of the lever l1 causes the projections of the wheel 20 to strike the projection 26 on the arm I turning the screw 19 which forces the opposite end of the lever I1, and consequently the wheel 22, inwardly against the flange 23 when the flange 23 is forced inwardly to seal the can, the wheel I2 is unscrewed allowing the arm I to be forced upwardly by the action of the spring 9 and the head 21 released from the can. The said head 21 is'shaped on its lower surface to hold the sealing ring.

Having thus described my invention, what I claim is:

A can-closing machine comprising a base, an upright adjustable in said base, an arm adjustable on said upright, a projection on the lower surface of said arm, means for adjusting said arm on said upright, a shaft revolubly mounted in one end of said arm, means for revolving said shaft, an arm rigidly secured to the lower end of said shaft, a lever pivoted to said last-named arm, a roller mounted in one end of said lever, a screw adjustable in the opposite end of said lever and having its free end impinging against the arm on the lower end of said shaft, and a. wheel on the opposite end of said screw having a plurality of projections each adapted to strike the projection on the lower surface of the firstnamed arm to turn said screw and force the roller in against the can being closed.
